Leucocytosis and severe pain due to ureteral calculi

Abstract

尿路感染症を合併していない尿管結石症例300例を対象として, 尿管結石による疼痛と血中白血球増多症について検討した.9, 000 cmm以上の白血球増多症が, 全例の87.7%に認められた.9, 000～12, 000 cmmの白血球増多症が, 全例の61%と, ほとんどの症例はこの範囲であった.22, 000/cmm以上の白血球増多症となる症例はなかった

We reviewed the outcome of 300 cases without urinary tract infections to determine the relationship between leucocytosis and severe pain due to ureteral calculi. Leucocytosis above 9, 000 cells per cmm was seen in 87.7% of the cases. Many patients (61%) had a leucocyte count between 9, 000 and 12, 000, but none had that exceeding 22, 000. This leucocytosis can be attributed to a transient distributional alteration by means of leucopheresis to circulation sites from a storage pool such as the blood vessels in the spleen, liver, lung, etc. Since leucocytosis often accompanies ureteral calculi, caution should be exercised in distinguishing it from appendicitis.
